HBO just dropped hints about what will be in the next 2 'Game of Thrones' episodes

HBO Warning: There are spoilers ahead for "Game of Thrones" season six including speculation of events.

"Game of Thrones" fans who follow the series closely can usually suss out clues from each episode's vague description and title.

Excitingly, HBO just released more information for episodes four and five, listed below.

Episode 4 — "Book of the Stranger" — will air Sunday May 15.

Tyrion strikes a deal. Jorah and Daario undertake a difficult task. Jaime and Cersei try to improve their situation.

Episode 5 — "The Door" — airs Sunday May 22.

Tyrion seeks a strange ally. Bran learns a great deal. Brienne goes on a mission. Arya is given a chance to prove herself.

Let's start by taking a closer look at "Book of the Stranger." The title alone hints at the Faith of the Seven. The Stranger is one of seven gods worshiped in the southern kingdoms and by the Faith Militant. We can probably expect to see a lot of the High Sparrow and his minions.

The Stranger is the least-worshiped god of the seven, however. According to book lore, it represents "death and the unknown," and often is depicted as a hooded, barely human figure.

Get hype though — guess which character had a horse named Stranger? Sandor Clegane. The Hound. CLEGANEBOWL IS HAPPENING. Maybe. At the very least, our bet is on The Hound returning in this episode.

Helen Sloan / HBO Tyrion striking a deal may have to do with the Sons of the Harpy. Perhaps Varys has found their leader, and Tyrion is ready to negotiate. Jorah and Daario's difficult task will be rescuing Daenerys from Vaes Dothrak and her Dothraki captors. But maybe Drogon will get there first and unleash the fiery rage we know he possesses.

Now let's take a closer look at "The Door" — a maddeningly vague episode title. There are doors all over the place in Westeros. Since we can't deduce much from the title alone, we'll have to focus on the description. Which, worth noting, has no mention of Jon Snow or the North. Neither did "Book of the Stranger," so clearly HBO is still keeping Jon Snow's plot on lockdown.

But we do know Tyrion will seek "a strange ally." Perhaps this is the mysterious red priestess we saw in the trailer. Teaming up with the Lord of Light and his magical followers would definitely be a different tactic for Tyrion, who generally shies away from religious mentions.

HBOThe last concrete clue we have is "Brienne goes on a mission." Our guess is Sansa sends her to the Riverlands, possibly to try and find Arya again. After all, neither Brienne or Sansa realize she is in Braavos, and her last known location was somewhere in the middle of Westeros.

Tune into "Game of Thrones" on Sundays at 9 p.m. on HBO to see if our predictions are correct.
